Aims: Epidemiological evidence indicates a protective effect of light to moderate alcohol consumption compared to non-drinking and heavy drinking. Although several mechanisms have been suggested, the effect of alcohol on atherosclerotic changes in vessel walls is unclear. Therefore, we explored the relationship between alcohol consumption and common carotid intima media thickness, a marker of early atherosclerosis in the general population. Methods: Individual participant data from eight cohorts, involving 37,494 individuals from the USE-IMT collaboration were used...

Preoperative evaluation of precise aneurysmal geometry is important for the treatment of intracranial aneurysms. We present two cases of unclippable side wall aneurysms due to their extremely low dome height, which appeared as saccular in the preoperative image because of a comparatively narrow atherosclerotic parent arterial lumen. In both cases, a calcified vessel wall was noted preoperatively. Lack of a definitive neck and abrupt discrepancy between the fragile aneurysmal wall and the atherosclerotic parent arterial wall was confirmed intraoperatively in both cases...

PURPOSE: Chronic obstructive pulmonary disease (COPD) and particularly emphysema are characterized by stiffness of the aorta, due in part to accelerated elastin degradation in the lungs and aorta. Stiffness of the pulmonary arteries (PAs) may also be increased in COPD and emphysema, but data are lacking. We assessed PA stiffness using MRI in patients with COPD and related these measurements to COPD severity and percent emphysema. MATERIALS AND METHODS: The Multi-Ethnic Study of Atherosclerosis (MESA) COPD Study recruited 290 participants, age 50-79 years with 10 or more packyears and free of clinical cardiovascular disease...

BACKGROUND: Ischemic and hemorrhagic stroke are increasingly recognized as heterogeneous diseases with distinct subtypes and etiologies. Information on variation in distribution of vascular risk factors according to age in stroke subtypes is limited. We investigated the prevalence of vascular risk factors in stroke subtypes in relation to age. METHODS AND RESULTS: We studied a prospective multicenter university hospital-based cohort of 4033 patients. For patients with ischemic stroke caused by large artery atherosclerosis, small vessel disease, or cardioembolism and for patients with spontaneous intracerebral hemorrhage or aneurysmal subarachnoid hemorrhage, we calculated prevalences of vascular risk factors in 4 age groups: <55, 55 to 65, 65 to 75, and ≥75 years, and mean differences with 95% CIs in relation to the reference age group...

REVIEW
Moon-Hyon Hwang, Sewon Lee
Insulin resistance associated with metabolic syndrome and Type 2 diabetes mellitus is an epidemic metabolic disorder, which increases the risk of cardiovascular complications. Impaired vascular endothelial function is an early marker for atherosclerosis, which causes cardiovascular complications. Both experimental and clinical studies indicate that endothelial dysfunction in vasculatures occurs with insulin resistance. The associated physiological mechanisms are not fully appreciated yet, however, it seems that augmented oxidative stress, a physiological imbalance between oxidants and antioxidants, in vascular cells is a possible mechanism involved in various vascular beds with insulin resistance and hyperglycemia...

Premise This review summarises the pain syndromes that overlap between headache and facial pain and overlap between pain and cranial nerve lesion. Problem These syndromes share two features in common. First, they show both cranial nerve impairment (e.g. palsy, autonomic dysfunction) and pain; second, they have inflammatory (and/or small vessel) processes as the underlying mechanism. A typical representative of these syndromes is recurrent painful ophthalmoplegic neuropathy, which was previously called ophthalmoplegic migraine and was regarded as a migraine subtype...

Lebanon is a developing country where the prevalence of stroke subtypes and their correlation with risk factors have not been studied, even though stroke management is an ongoing major national healthcare challenge. In a retrospective study conducted in two university hospitals, data were collected on all stroke cases admitted in 2012 and 2013. Ischemic strokes were then classified according to a modified TOAST classification. A total of 254 inpatients (mean age 68.41 years ±13.34, 55.1% males) was included in the study; of these, 15% had had a hemorrhagic stroke and was therefore excluded...

Vasculitides, particularly those affecting small vessels, are known to complicate systemic lupus erythematosus (SLE); however, isolated venulitis of the mesenteric bed has rarely been reported. Here we relate the case of a 46-year-old woman with SLE who presented with acute abdominal pain due to artery thrombosis and extended splenic ischemia requiring splenectomy. The histological examination revealed diffuse venulitis in the absence of arterial vasculitis consistent with the definition of mesenteric inflammatory veno-occlusive disease (MIVOD)...

Coronary artery aneurysm is defined as a coronary dilation that exceeds the diameter of adjacent segments or the diameter of the patient's largest normal coronary vessel by 1.5×. It is an uncommon disease that has been diagnosed with increasing frequency since the widespread appearance of coronary angiography. The published incidence varies from 1.5% to 5%, suggesting male dominance and a predilection for the right coronary artery. Although several causes have been described, atherosclerosis accounts for ≥50% of coronary aneurysms in adults...

BACKGROUND: A low serum total bilirubin (T-bil) level is associated with an increased risk of atherosclerosis. However, the differential impact of the serum T-bil level on cerebral atherosclerosis and cerebral small vessel disease (SVD) is still unclear. METHODS: We evaluated serum T-bil levels from 1,128 neurologically healthy subjects. Indices of cerebral atherosclerosis (extracranial arterial stenosis [ECAS] and intracranial arterial stenosis [ICAS]), and indices of SVD (silent lacunar infarct [SLI], and moderate-to-severe white matter hyperintensities [msWMH]) were evaluated by the use of brain magnetic resonance imaging (MRI) and MR angiography...

BACKGROUND AND AIMS: The severity of obesity is evaluated by visceral-to-subcutaneous fat ratio (VS ratio), which may be useful for predicting atherosclerosis. However, it is unclear how VS ratio affects different types of cerebrovascular lesions. This study was conducted to evaluate the clinical impact of visceral fat accumulation on the cerebrovascular lesions. METHODS: This cross-sectional study included 980 apparently healthy Japanese adults who underwent a health check-up program focused toward atherosclerosis, between 2011 and 2014...

There is a strong association between lipoprotein-associated phospholipase A2 (Lp-PLA2) levels and atherosclerosis-related diseases. The aim of this study was to investigate the role of Lp-PLA2 in the ischemic stroke and further offer clinical evidence that measuring Lp-PLA2 helps predict the risk of stroke occurrence and recurrence. A total of 328 hospitalized patients were recruited, including 179 cases of acute cerebral infarction (ACI) and 149 non-ACI controls. The serum level of Lp-PLA2 in ACI was significantly higher than non-ACI...

OBJECTIVE: Whether dynamic cerebral autoregulation (dCA) is impaired focally in the affected hemisphere or bilaterally in both the affected and nonaffected hemispheres after ischemic stroke remains controversial. We therefore investigated the pattern of dCA in acute ischemic stroke patients with different subtypes. METHODS: Sixty acute ischemic stroke patients with unilateral anterior circulation infarct [30 with large artery atherosclerosis (LAA), 13 with small vessel disease (SVD), and 17 with coexisting LAA and SVD] and 16 healthy controls were enrolled...

This study was conducted to investigate the role of different homocysteine metabolism-related vitamin (HMRV) levels in the correlation between hyperhomocysteinemia (HHCY) and ischemic stroke (IS) subtypes. Three hundred and forty-eight IS patients manifesting different vascular subtypes were subclassified on the basis of HMRV deficiencies. Correlation between HHCY and IS subtypes was investigated in all the subgroups. In this study, HHCY was significantly correlated with the IS subtypes in large artery atherosclerosis (OR 1...

Importance: The ability of present-day etiologic stroke classification systems to generate subtypes with discrete stroke characteristics is not known. Objective: To test the hypothesis that etiologic stroke subtyping identifies different disease processes that can be recognized through their different clinical courses. Design, Setting, and Participants: We performed a head-to-head evaluation of the ability of the Causative Classification of Stroke (CCS), Trial of Org 10172 in Acute Stroke Treatment (TOAST), and ASCO (A for atherosclerosis, S for small-vessel disease, C for cardiac source, and O for other cause) classification systems to generate etiologic subtypes with different clinical, imaging, and prognostic characteristics in 1816 patients with ischemic stroke...

Hydrodynamic flow is an essential stimulus in many cellular functions, regulating many mechanical sensitive pathways and closely associating with human health status and diseases. The flow pattern of blood in vessels is the key factor in causing atherosclerosis. Hemodynamics has great effect on endothelial cells' gene expression and biological functions. There are various tools that can be used for studying flow-induced cellular responses but most of them are either bulky or lack precise controllability. We develop an integrated microfluidic device that can precisely generate different flow patterns to human endothelial cells cultured on-chip...

Matrix metalloproteinase-2 (MMP-2) is involved in the pathophysiology of stroke. Previous studies have shown that MMP-2 activity is increased in stroke; however, evidence of epigenetic regulation of the MMP-2 in stroke is still limited. We examined methylation of the MMP-2 promoter in patients with ischemic stroke. This study included 298 patients with ischemic stroke and 258 age-matched and sex-matched controls. MMP-2 promoter methylation levels were measured by pyrosequencing at eight potential cytosine-guanine (CpG) sites...
